The Diagnostic Accuracy of Serum Alpha-Fetoprotein Levels in Follow-up for Recurrence of Sacrococcygeal Teratoma; a Nationwide Review of SCT Cases in the Netherlands

In brief

This nationwide Dutch study evaluates the diagnostic accuracy of serum alpha-fetoprotein (AFP) as a tumor marker for detecting recurrent sacrococcygeal teratoma after initial surgical resection. The research examines normal AFP dynamics post-resection and assesses its reliability in surveillance protocols for this rare pediatric tumor.

• Serum AFP is commonly used to monitor for sacrococcygeal teratoma recurrence after initial resection.
• Understanding normal AFP dynamics post-resection is critical to distinguish physiologic decline from pathologic elevation.
• AFP diagnostic accuracy varies; false positives/negatives can occur, requiring correlation with imaging and clinical findings.
• Nationwide data provides evidence-based benchmarks for AFP surveillance protocols in pediatric SCT follow-up.
